16.4.3
In Full-Bridge Output mode, four pins are used as out-
puts; however, only two outputs are active at a time. In
the Forward mode, pin RC2/CCP1/P1A is continuously
active and pin RD7/PSP7/P1D is modulated. In the
Reverse mode, RD6/PSP6/P1C pin is continuously
active and RD5/PSP5/P1B pin is modulated. These are
illustrated in Figure 16-6.

P1A, P1B, P1C and P1D outputs are multiplexed with
the PORTC<2> and PORTD<5:7> data latches. The
TRISC<2> and TRISD<5:7> bits must be cleared to
make the P1A, P1B, P1C and P1D pins output.
